“If your job or studies involve reading through longer works, … you’ll forget how you ever read without it.”

-Editors’ Choice, Most innovative ipad app of the year, Apple, App Store


“…a deep and complete productivity tool for students, academics, and businesses... it proves hugely flexible in helping to collect, retain, and even create new information.”

-MacWorld, 2016




LiquidText evolved from: four years of research, two peer reviewed papers, and a PhD from Georgia Tech, by its founder Craig Tashman. The research focused on “active reading” where users highlight, annotate, search and take notes when working on a project. Key was understanding the limitations imposed by physical books and paper; and the opportunities created by powerful, mobile and desktop devices.

LiquidText’s efficient, integrated workflow and elegant note taking tools improve productivity by reducing work time and increasing the clarity of the work product.

...an app that may forever change how you read and
annotate complex documents.

“This app doesn't follow the usual PDF workflow playbook but instead is engineered around the idea of reviewing long PDF documents better.”

-MacSparkey, David Sparks, 2016


“…wholly unlike any other PDF app on the market.... there's no better app than LiquidText out there — and possibly no better workflow.”

Every project in LiquidText creates a document pane and infinite workspace. The document pane imports and contains all relevant documents, including live user annotations, highlites and connections. Notes, ideas, excerpts, images and connections are written, typed and/or placed on the workspace.

LiquidText makes gathering notes and excerpts frictionless; users do it naturally, pulling out references as they read and dropping them on the workspace. LiquidText allows the user to organize the workspace as they prefer making notes and connecting them to others in the form of a list of notes and/or as mind maps.

LiquidText delivers an intuitive user experience that allows for increased efficiency, organization and reasoning.

connect notes and sources (from Kanov) - with shadow.gif



LiquidText uses ink in a unique way. Users can draw lines between document contents, notes, or anything in the app; between, within and among multiple documents and notes. From these connections you get visual hyperlinks which call out the connections at a touch. LiquidText helps you see these relationships along with relevant source context.

With LiquidText, supporting sources and context are never more than a single click away.

Using this tool, researcher’s ideas, observations and insights are visually linked with source materials and other related notes. Collaborators and reviewers see not only results, but the network of interrelated sources, observations and notes which support the author’s conclusions with unprecedented transparency and clarity.

Not only does this tool enable a user to select text and turn it into a note, it also facilitates comprehension of a group of notes by creating relations among them in an intuitive and engaging manner.
